Other AbstractTo obtain accurate estimation of the heave position, an adaptive digital filter is proposed to improve the estimation accuracy of a vessel’s heave motion. The double-integration of the heave acceleration measured from the inertial measurement unit (IMU) is processed by the adaptive digital filter. The experiment results show that, compared with the traditional digital filter which uses the real heave motion data from the “Da Yang Yi Hao” scientific research vessel, the proposed adaptive digital filter reduces the mean variances of the position deviation by 80% and 85% at level 4 and 5 sea state respectively, which demonstrate that the adaptive digital filter can significantly improve the estimation accuracy of a vessel’s heave motion.
